The attOwner attribute is encoded as counted strings laid end-to-end. The format for attOwner is as follows:

attOwner:

display-name-length display-name address-length email-address

email-address

type : address

Unlike other length values, the display-name-length and address-length are unsigned 16-bit values instead of unsigned long integers. They still include terminating null characters, however. The type and address strings in the email-address entry are separated by a literal colon (:) character, such as "smtp:joe@nowhere.com". Only the combined type **:**address string is null-terminated.

The mapping of MAPI properties to the attOwner attribute is dependent on the message class of the message being encoded.
